Biology Core 9. Differentiate between the previous five-kingdom and current six-kingdom classification systems. Objective B.9.5: Differentiate among the major characteristics of the six kingdoms. Additional content to be taught: Identifying ways in which organisms from the Monera, Protista, and Fungi kingdoms are beneficial and harmful Examples: beneficial—decomposers, harmful—diseases • Writing scientific names accurately by using binomial nomenclature 11. Classify animals according to type of skeletal structure, method of fertilization and reproduction, body symmetry, body coverings, and locomotion. Examples: reproduction—sexual, asexual; locomotion—cilia, flagella, pseudopodia Objective B.11.2: List types of body coverings and locomotion found in animals. Objective B.11.5: Describe the types of reproduction as asexual or sexual..

Protist... For your foldable 1. Fold your paper in half -hamburger fold-then in half again....to make a booklet 2. On the front... Write as shown on the next page: Protist... the Outcast! 4

Protists The Outcasts

Open the foldable so 2 sides show Copy the information on the next slide on these two sides 6

Protists Animal-like Plant-like Two Subcategories: All Eukaryotic All live in moist environments Two Subcategories: Some unicellular Others multicellular Animal-like Some heterotrophs Others autotrophs Plant-like Most one celled microscopic Others 300 feet long!

Animal-like Protists Subdivided: Mode of Locomotion Pseudopodia Cilia Protozoans Animal-like Protists All unicellular All heterotrophic Subdivided: Mode of Locomotion Pseudopodia Cilia Flagella

Open foldable all the way so 4 boxes show The top two boxes will show animal like protist (protozoans).... amoeba and paramecium The bottom two boxes will show plant like protist.... euglena and volvox Draw the simplified pictures on the chart paper and label the parts then copy the info on the next slides 9

Animal-like Protists Amoeba They move by extending a part of their body forward, and pulling the rest of its body behind it Pseudopodia – finger-like projections that extend outward - Also used to trap food Amoeba www.youtube.com/watch?v=W6rnhiMxtKU Text

Animal-like Protists with Cilia Paramecium They move by beating tiny hair-like structures called cilia The cilia act as tiny oars that allow the protist to move through its watery environment. They also push food into the mouth area called the “oral groove” Paramecium with Cilia

Other Animal-like Protists with Flagella They move by beating their long whip-like structures called flagella. May have one or more flagella Some are parasitic and cause diseases Giardia Tsetse Fly Diarrhea Trypanosoma African Sleeping Sickness

Another Disease-causing Protozoan... Female Anopheles mosquito Plasmodium falciparum Malaria

Plant-like Protists Four basic groups: Euglenoids Dinoflagellates All autotrophic Plant-like Protists Produce oxygen Form the base of aquatic food chains Four basic groups: Can be unicellular, multicellular, or live in colonies Euglenoids Dinoflagellates Diatoms Algae

Euglena M Photosynthetic Unicellular Moves by Flagellum ext Unicellular Moves by Flagellum Eyespot detects light so it can do photosynthesisext 12

Volvox Plant-like Protists Mostly unicellular, but form colonies with 1000-3000 cells living together Each individual cell has 2 tiny flagella that make the colony roll Volvox Green Algae Volvox Daughter colonies will be released
